Trial Arms

Palbociclib and INCMGA00012ExperimentalOne treatment cycle will consist of 28 days. Patients in both study phases will start palbociclib on Day 1 and INCMGA00012 on day 15 (+/- 7 days) of each cycle at the following dose schedule: INCMGA00012: 500 mg IV (flat dose) q28 days Palbociclib: 125 mg PO daily for 21 days, followed by 7 days off, q28 days Palbociclib will be taken on Day 1 of each cycle for 21 consecutive days followed by 7 days off (days 22-28 of each Cycle). INCMGA00012 will be administered on Day 15 of (+/- 7 days) each cycle and repeat every 28 days.

Maximum Eligible Age:N/A

Eligible Gender:All
Healthy Volunteers:No

Primary Outcome Measures

Measure:confirm the recommended phase two dose (RP2D
Time Frame:within 6 weeks of treatment
Safety Issue:
Description:DLTs will be assess within the first 6 weeks of the treatment combination . DLT definitions are described in section 15.4, and will be defined using NCI CTCAE v 5.0. If ≤ 1 patient out of 6 has a dose-limiting toxicity, the dosing used in the safety lead-in phase will be declared the recommended phase 2 dose. If ≥ 2 of 6 patients in the safety lead-in experience a DLT, study treatment will be halted and no further patients will be enrolled. If the study is resumed with an alternative dosing schema, a new safety lead-in phase will be completed with the new dosing regimen

Secondary Outcome Measures

Measure:best overall response rate
Time Frame:48 weeks
Safety Issue:
Description:defined by RECIST v1.1


Phase:Phase 2
Primary Purpose:Interventional
Overall Status:Recruiting
